VIDEO: The Gedser wind turbine during NASA test runs
Thanks to Kristian H. Nielsen we can present this unique video of the Gedser wind turbine in action. Kristian H. Nielsen, associate professor and head of the Center for Scientific Studies at Aarhus University, released the video in 2010 when he published a journal article comparing the technological development of the Gedser mill and the Smith-Putnam wind turbine. You can request a copy of his article (click here) at Researchgate.net.

From August 21 to 31, 1961, Johannes Juul took part in the UN conference on new sources of energy in Rome. His lecture "Design of Wind Power Plants in Denmark" was received with a standing ovation by the assembly. In 1977-1979, as a result of the energy crisis of the early 1970s, NASA and the Department of Energy (DOE) initiated test runs of the Gedser wind turbine for the US energy program.

Press clipping from the Danish newspaper "Ny Dag", April 26, 1977:
"Travel to the US to discuss wind turbines
Next week, engineer Mogens Johannsen from the Association of Danish Electricity Companies will travel to the USA together with project manager Vagn Rasmussen from the regional electricity company SEAS to discuss wind turbines. Project financing for the Gedser wind turbine is now secured. State funds amounting to 11.2 million Danish kroner and 3 million Danish kroner from the Electricity Works Association have been made available."

Press clipping from the trade magazine "Ingenioeren", October 17, 1976:
"USA shows great interest in the Gedser mill
The Gedser Mill aroused great interest among Americans. What is particularly important here is the simplicity and robustness of the construction, but also because the concrete tower and the three rotor blades are very different from wind turbines built in the USA. In the USA, mainly steel lattice towers with only two rotor blades are built."

Press clipping from "Lolland-Falster Folketidende", September 9, 1976:
"Rotor blades are removed
The rotor blades of the Gedser mill were removed with a large crane over the last two days. Afterwards, the nacelle should be removed to see whether the faulty parts can be repaired. If it turns out that this can be done economically, tests will then be carried out to show whether and how wind energy can be used."

"New rotor blades on the Gedser mill
The American energy research organization ERDA has been entrusted with carrying out the task and is contributing to the costs of repairing the mill. The photo shows the large hub and gear of the mill."

"Measuring program initiated at the mill
The Gedser Test Group, with representatives from the Atomic Research Center in Riso, the Marine Engineering Laboratory in Copenhagen and Denmark's Technical University, is responsible for carrying out the measurement program, while the electricity company SEAS is responsible for operating the mill. The generator and gearbox are attached to the top of the mill. They are examined here by Hans Schmidt from the Sonderjyllands Maskinfabrik. (Photographer: Anders Knudsen)".
